Problem establishment call ISDN

[nuria.andres]

HI,

I have a router 1841 (C1841-ADVENTERPRISEK9 - Version 12.3(14)T7), and it doesn?t work the call ISDN.

The log is:

Hola,

can you check if your ISDN interface is actually connected to an ISDN and not a regular phone line ? Can you post the configuration of your router ?

I initially agreed that the first several messages look like the ISDN was not working. But these messages I believe indicate that it did work:

.Sep 8 12:03:31: ISDN BR0/1/0 EVENT: service_queue_from_physical_layer: Recvd L1 prim ISDN_PH_ACT_IND state is IF_ACTIVATING

.Sep 8 12:03:31: ISDN BR0/1/0 EVENT: isdn_sw_cstate: State = 4, Old State = 4

I believe that these indicate that the connection did establish - and in less than a second the other end terminated the call.

I believe that it would be helpful to have the output of debug ppp negotiation and of debug ppp authentication.
